Abstract
PALLARES MUNOZ, Myriam Rocío and RODRIGUEZ CALDERON, Wilson. Modeling of forced vibration phenomenon by making an electrical analogy with ANSYS finite element software. Ing. Investig. [online]. 2009, vol.29, n.1, pp.5-12. ISSN 0120-5609.
Designing mechanical systems which are submitted to vibration requires calculation methods which are very different to those used in other disciplines because, when this occurs, the magnitude of the forces becomes secondary and the frequency with which the force is repeated becomes the most important aspect. It must be taken care of, given that smaller periodic forces can prompt disasters than greater static forces. The article presents a representative problem regarding systems having forced vibration, the mathematical treatment of differential equations from an electrical and mechanical viewpoint, an electrical analogy, numerical modeling of circuits using ANSYS finite element software, analysis and comparison of numerical modeling results compared to test values, the post-processing of results and conclusions regarding electrical analogy methodology when analysing forced vibration systems.
